An embodiment provides a method of preparing a pattern. In the pattern preparing method, when mask patterns corresponding to on-substrate patterns are prepared to form the on-substrate patterns corresponding to design patterns, the mask patterns are prepared based on a correlation which needs to be satisfied between the design patterns so that a relation which same the correlation can be satisfied between the mask patterns corresponding to the design patterns.

A method of optimizing a semiconductor device manufacturing process according to an embodiment is a method of optimizing a semiconductor device manufacturing process in which a pattern based on circuit design is formed. The method of optimizing a semiconductor device manufacturing process according to the embodiment includes: at the time of calculation of a statistic amount based on a distribution of differences at a plurality of sites between a pattern formed by a first exposing apparatus in a first condition and a pattern formed by a second exposing apparatus in a second condition, calculating the statistic amount after applying weighting to the differences based on information on an electrical characteristic; and repeating the calculating with the second condition being changed, and selecting an condition in which the total sum becomes a minimum or equal to or less than a standard value as an optimized condition of the second exposing apparatus.

A method for verifying mask pattern data includes preparing design circuit data on a design circuit which realizes a desired electrical operation. Data on a design circuit pattern having a structure which realizes the design circuit on a semiconductor substrate is prepared. Mask pattern data on a pattern of a mask used in order to produce the design circuit pattern is prepared. A circuit pattern which is to be obtained by processing a film using the pattern of the mask indicated by the mask pattern data is acquired. Circuit data on a circuit realized by at least a first part of the circuit pattern is produced. A circuit mismatch part where the circuit data and a part of the design circuit data which corresponds to the first part of the circuit pattern do not match up is detected.

A pattern verification method includes preparing a desired pattern and a mask pattern forming the desired pattern on a substrate, defining at least one evaluation point on an edge of the desired pattern, defining at least one process parameter to compute the transferred/formed pattern, defining a reference value and a variable range for each of the process parameters, and computing a positional displacement for each first points corresponding to the evaluation point, first points computed using correction mask pattern and a plurality of combinations of parameter values obtained by varying the process parameters within the variable range or within the respective variable ranges. The positional displacement is a displacement between first point and the evaluation point. The method further includes computing a statistics of the positional displacements for each of the evaluation points, and outputting information modifying the mask pattern according to the statistics.
